I do love the textural consistency of slices. Their bases can range from crunchy to cake like. The topping can be as simple as some icing to a more complex multi layer creation.
This apple walnut crumble slice isn’t too difficult or time consuming if you are using a food processor. The base falls into the crunchy category and is biscuit in style. It has a simple filling of stewed apples which is then topped with a walnut crumble laced with cinnamon and nutmeg.
If you are a fan of apple crumble, then you will be a fan of this slice.
I generally serve my apple walnut crumble slice once cooled, simply dusted with icing sugar (confectioners sugar). But you could also serve this slice straight from the oven with a nice big scoop of vanilla bean ice cream. A drizzle of caramel sauce wouldn’t go astray either.
The walnuts in the crumble are easily swapped out for your favourite nut. Pecans or almonds would be a tasty alternative.
The simple apple filling could also be spruced up a little. This is easily done with the addition of a handful of dried sultanas or chopped dried apricots.
As I keep saying to you guys, don’t leave your imagination at the kitchen door. If you have a great base recipe that the family loves, play around and change it up.

- 60 ml ¼ cup iced water
Apple Filling
- 6 granny smith apples

- 2 teaspoons vanilla bean paste

- 125 g 2/3 cup plain flour
- 60 g butter
- 10 g 2/3cup walnuts chopped
Instructions
- Preheat oven 180 deg C (360 deg F). Grease and line a 20cm x 30cm lamington tin with baking paper. Extend the baking paper 5cm above the edges of the tin.
- In a food processor place plain flour, cornflour, baking powder and butter. Process until fine crumbs form.
- If you don’t have a food processor, place plain flour, cornflour, baking powder and butter (cut into small cubes) into a large bowl. Rub the butter through the dry ingredients with the tips of your fingers until the mixture resembles a fine crumb.
- Add egg and cold water, process until the pastry dough comes together. If not using a food processor mix with a spoon and then knead until just combined.
- Press dough into prepared lamington tin, evenly, until the base of the tin is covered.
- Place lamington tin in the refrigerator for 20 minutes to chill.
- While the base of the slice is chilling and then baking prepare the apple filling and walnut crumble.
- Once chilled line pastry dough with a piece of baking paper. Top the baking paper with baking weights or uncooked rice.
- Place in the oven and blind bake for 15 minutes or until the edges have just started to brown.
- Remove baking weights (or rice) and baking paper. Bake for a further 8 – 10 minutes until base is lightly golden and remove from oven.
- Increase oven temperature to 200 deg C (390 deg F).
- Spread apple filling over the top of the pastry base and then top with the walnut crumble. Bake for 30 minutes or until the crumble is golden.
- Cool on a wire cooling rack. Once cooled sprinkle with icing sugar and cut into squares.
Apple Filling
- Place apple slices with 125ml (1/2 cup) water in a large saucepan. Over a medium heat bring the mixture to a boil. Reduce heat, cover and simmer for 10 minutes. Stir occasionally, when apples are tender they are ready. Drain well.
